Rear axle whine

Yeah, I guess that rules out "wheelie bars" as a possible explanation as well

Actually, I've come across *similar*, seemingly superfluous devices before, though on more modern cars, and apparently they were
harmonic vibration dampers of some sort. Ironically one of their functions was to absorb the "Rear axle while" of the subject line!

My old mk3 Supra had some big rubber mounted metal lumps on the rear subframe called "diff dampers" in the manual. Mine fell off
(due to axle tramp ironically) after a spot of drag racing at the Pod, and I could hear the diff whine slightly at motorway speeds
afterwards which I'd never heard before.

Anyway, if you want to experience axle-tramp in a Viva, just put a 200lbft V6 in it!
Believe me I really miss the Jag IRS I had on by old HC, but I'm not sure 5" rear arch extensions would suit a HB, even though they
looked great on the HC. Check this out for its awesome rear-end:

Just a bit of useless info?    Those funny protuberances as you call them, are called harmonic dampers. These were fitted to the Viva E coupe only, because these cars mysteriously suffered from a droning/drumming at a certain speed range.    Note that one is bigger than the other,  and the core inside the eye is actually made of wood. 
That's all for now folks

Haven't you got a trolley jack Paul? It makes lifting the axle into position a doddle from what I remember, though mines a 3-ton
jack which has quite a big lifting cup so once you sit the diff on there it stays there for the whole ride, as it were.
 
As an aside, lifting the big axle from the Rover's boot last night I was surprised it didn't seem much heavier than the small one.
Still those funny protruberances on that old axle must weigh a fair bit
BTW, is there oil in that big axle? If so is it old or new?

Just to let you all know the axle was fitted in an hour on me own.... only problem i had was those damn silly counterbalance weights (ala E coupe) The fowl the handbrake cable so remmoved them... Shame as it looked like the car had wheeelie bars ! LOL.

All i have to do now is bleed the brakes and fill the axle oil up... then take it for a drive and see if its good!

[pbottomley]

well bleed the brakes (well sort of as they sort of work now) and yopped up the oil in the axle, been up the road about a mile and back... the diff whine has gone thabnk god..... But it seesm that was maskingall the other weird squeaks etc SO now i have all of those to find and put right !!

Typical sort one thing get 20 more to do
